I managed to sort a few installation obstacles and I was getting excited with Sabayon. However... I find no way (certainly no EASY simple way) to install an Epson printer-scanner. Drivers are available as deb files (also as rpm) and easily installed with Gdebi and printer setup in deb derived systems. I tried several times with CUPS, ipp, http, etc. What am I missing or doing wrong that I cannot solve what should be a standard common action (installing an epson printer/scanner )?

ADDED: Following the instructions, I can print with Cups+Gutenprint. However, only somewhat workable option is using NX420 (NO NX430 option) and color graphs do not print well. Besides, how do I get scanning?

Is there a simple CLI to use the deb (or the rpm) drivers available from Epson/Seiko? Any other solution? I am an ignorant newbie trying to avoid all CLI dealings!
